-box and supporting plate therefor.

Be it known that I, JOHN B. WATLING, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Safety-Boxes, of which the following is a full, clear, and exact description.

The invention relates to safety boxes and more particularly to cash boxes for coin controlled machines.

Coin controlled machines are frequently exposed in public places and the present invention seeks to provide a cash box for receiving the deposited coins which is of strong construction and which is securely guarded so that access thereto cannot be readily attained except by the person holding the cash box key.

The invention consists in the features of construction 'hereinafter set forth, illustrated inthe preferred form in the accompanying drawings and more particularly pointed `out in the appended claims.

In the drawings, Figure 1 is a view in elevation, partly broken away 0f the cash Fig. 2

is a longitudinal section taken through the machine casing and the cash box. Fig. 3 is a rear elevation of the'fas'tening devices for holding the cash box -in position, the latter being shown in section on the line 3 of Fig. 2. Fig. t is a detail horizontal section on the line 4l of Fig. 3. Fig. 5 is a detail vertical section on lthe line 5 of Fig. 3.

In the construction shown the casing 10 of the'coin controlled machine is formed of sheet metal and the cash box is secured to the rear face of one of the vertical walls 11 of the casing.

"Ihe-cashbo'x comprises upper and lower end walls 12, a back wall 13 and side walls 14 which are preferably formed of sheet metal. The back and side walls 13 and 14 are formed of a single piece of sheet metal and are provided at their upper and lower ends with inturned Vflanges 15 which overlap theedges of the upper and lower end walls 12 and are secured thereto preferably by spot welding. At their front edges the side walls'lf are provided with inturned flanges 16 of considerable width and the upper-and lower end walls 12 are also provided at their front edges with inturned flanges 17 which, at the corners of the box oveflap the flanges 16 as most clearly shown in Fig. 5. The flanges 16 and 17 constitute the front wall of the box and surround a rectangular opening 18 in such front wall. These flanges abut against the rear face of the supporting plate or wall 11 of the machine casing, such wall or plate being provided with a rectangular opening 19 therein which registers with and is preferably of the same size as the opening 18 in the front wall of the box.

Suitable fastening devices which are accessible for releasing the same only from the inner side of the supporting plate 11 i and preferably only from the interior vof the box, are provided for securing thelatter to the supporting plate. In the preferred construction such fastening devices also serve to secure in place a heavy rectangular frame 20, which abuts against the outer face of the supporting plate or wall 11 and surrounds the opening 19 therein. In the prefer-red construction shown, the rectangular cast-metal frame 20 is provided on its outer face with a raised rib 21 which extends about the opening therein, and on its inner face the frame is provided with a series of integral bosses 22 which extend through holes 23 formed in the supporting plate 11 and in the flanges 16 and 17 as most clearly shown 4in Figs. f1 and 5, each of the bosses having a tapped hole for receiving a fastening tap-bolt 2 4. ln the construction shown there are six of these fastenings at each of the corners of the cash box and two intermediate its upper and lower ends., In the latter two fastenings, the bosses 22 extend through the 'supporting plate or wall 11 and through the side flanges 16 and spacingcollars surround the inner ends of the bosses. At the corners of the box the bosses 22 extend through the supporting plate or wall 11 and also through both the side and end flanges 16 and 17 as shown in Fig. 5, and short cross straps 26, one at each end of the box have openings therein into which the inner portions of the bosses 22 extend. The sl'aacing collars and straps V25 and 2G abutagainst the inner faces of theflanges 16 and washers 27 are interposed -between the heads of the tap-bolts 211 and the inner faces of the spacing collar andl straps. The headed inner ends of the tap-bolts are polygonal in outline so that they may be readily engaged by a suitable wrench. These fastening devices serve to securely hold the cash box and the frame said fastening 20 in position and the latter serves to strengthen the edges of the openings in the supporting plate and in the box.

The inner edges 28 of the frame 20 are slightly beveled and are spaced from lthe inner edges of the openings 1S and 19 and a heavy cast metal door or cover plate 29 having correspondingly beveled edges fits snugly within the frame with its inner face closely adjacent or abutting against the edge portions of the opening 19 in the supporting plate 11. The door as shown, is provided on its inner face with an integral strengthening rib 30 and at its lower end with an integral, inwardly and downwardly projecting, angle lug 31 which is adapted to overlap the cross strap 2G at the lower edge of the box opening. A loclr-32 is secured to the inner face of the door adjacent its upper edge and is provided with a key nose 33 which is arranged within an opening formed in the cover. The bolt 34 of the lock is adapted to overlap the upper Harige 17 and project well behind the cast metal frame 2O so that the door can only be removed by iirst withdrawing the bolt by means of the lock key. The beveled edge door fits snugly within the beveled edge of the frame 2O and the rib portion 21 of the latter projects outwardly beyond the edge of the door so that it is exceedingly diicult if not impossible to insert an instrument between the frame and the edge of the door and pry the latter from position. rlhis guarding and strengthening frame 20 and the cash box are secured in place by fastening devices which are not accessible either from the exterior or the interior of the machine casing when the cover plate or door 29 is in position and locked. Hence, only the holder of the key to the look 32 can have access to the cash box. As in other coin controlled machines, a coin chute 35 leads into the upper end of the cash box.

It is obvious that changes may be made in the details set forth without departure from the essentials of the invention as delined in the claims.

I claim as my invention l. 1n safety boxes, the combination of a box, a supporting plate therefor, said box and said plate having registering openings, fastening devices accessible only through said openings for securing said box to said plate, and a cover for said openings, substantially as described.

2.
